In France, the air temperature is often 30 degrees in summertime. In the northern US, it's often 30 degrees in the winter. What's the most likely reason for this?

• Winters in the northern US are extremely warm

• France uses the Celsius scale, the US uses the Fahrenheit scale

• Summers in France are extremely cold

• France uses the Celsius scale, the US uses the Kelvin scale

How is the Kelvin scale different from the Fahrenheit and Celsius scales?

• The Kelvin scale is used in the US, the Fahrenheit and Celsius scales are used in Europe

• The Kelvin scale measures a wider range of temperatures than the other scales

• The Kelvin scale has no negative numbers

• The Kelvin scale does not exist outside of science labs

Where might you find a temperature of 2 kelvin?

• The North Pole

• The equator

• Earth's core

• The coldest regions of outer space

Why does warm air rise?

• Because it's less dense than cold air

• Because it's more massive than cold air

• Because it has a smaller volume than cold air

• Because it has more energy than cold air
